PACKING FOR LIGHT-SENSITIVE LAYER-CARRIERS.

ooaeeo.

To aZZ whom it may concern:

Be it known that I, Josnrn Soi-nruox, a citizen of the German Empire, and residentof Steglitz, near Berlin, Germany, have invented certain new and useful Improvements in and Relating to Fackings for Light-Sensitive Layer-Carriers.

The packing and the device for changing the layer carriers therein are so constructed that as well the insertion of the packing into a box for exposing same as the removal of the layer carriers from the box after exposure can be effected in daylight.

The invention is illustrated on the accompanying drawing.

Figure 1 shows a longitudinal section through one embodiment of the new packing. Fig. 2 is a top view of the packing. Fig. 3 shows the packing of Figs. 1 and 2 inserted into a carrying frame. Fig. 4 is a longitudinal section through a modified form of the packing in connection with a modified form of a carrying frame, the carrying frame and the packing forming together a whole. Fig. 5 is a cross-section along the section line of Figs. 3 and t. Fig. 6 is a longitudinal section through a change box into which a packing containing carrying frame in accordance with Figs. 3 and 1 may be inserted for the purpose of successively exposing the layer carriers. Fig. 7 is a top view of the change box, shown in longitudinal section in Fig. 6, showing the said carrying frame inserted therein. Fig. 8 is a longitudinal sect-ion through Fig. 7. Fig. 9 is a fragment of the device illustrated in Fig. 8, the elements of the device being shown in different position. Fig. 10 is a longitudinal section througha modified form of the packing provided with a two chambered packing room. Fig. 1 shows the packing of Fig. 10 inserted into a suitable changing and exposing box. Fig. 12 is a perspective representation of a layer carrier provided atone end with gripping openings and connected to a light-proof interposition sheet.

In. the embodiment of the packing represented in Fig. 1 the layer carriers are indicated by dotted lines and designated with the reference numeral 1. The light-tight interposition sheets are designated 2. \Vith regard to the clearness of the drawing in Fig. 1 only two layer carriers and two interposition sheets are indicated. In prac- Specification of Letters Patent.

tice however every packing contains preferably a greater number of layer carriers and interposition sheets. The frame of the packing is open at one broad side. The light-tight closure is effected on this side by one of the light-tight sheets 2. The interposition sheets 2 extend from the package through a slit, which is light-tightly closed by a ledge 3 of velvet or like material. A springy plate 41 in the interior of the packing casing is provided for pressing the pile of layer carriers against the exposing plane. The numeral 5 designates a stop member provided at the bottom of the packing. The purpose of such stop member will be mentioned later on. 6 is a closing member at one end of the packing which is provided with extension rods 7 guided in the packing frame at the upper side of the layer carrier pile. 8 is a gripping member, firmly connected to the packing and provided with a pin 9, for fixing the ends of the light-tight interposition sheets 2 extending through the above mentioned slit of the packing. 10 is a bottom of a carrying frame or casing into which the packing can be inserted. The frame-like casing is provided with lateral guides 11 for the packing, which is carried therein, as shown in Fig. 5. The free space 12 between the bottom plate 10 and the packing inserted into the carrying frame forms a collecting chamber for the exposed layer carriers. The collecting chamber 12 is closed at the front end by a ledge 13.

In the embodiment of the packing carrying frame shown in Fig. 3 the collecting chamber can be closed at one end by a door 14- which is secured in its closed position by springy members 15.

16 is a springy pawl adapted to grasp behind the closing member 6 of the packing shown in'Figs. 1 and 2.

in the embodiment of the carrying frame shown in Fig. lthe door 1 1 is dispensed with, because in this instance the end member 17 of the carrying frame effects itself the closing of the packing room at one end. The carrying frame in the case of Fig. 4 there fore forms one part of the packing.

The changing and exposing box represented in Fig. (3 is provided at one end with a closing door 18 and has at its other end an opening 19 above a ledge 20, said opening forming a passage for the packing. 21 are packing illustrated in Fig. 10 is inserted into the changing and exposing box in the direction indicated by the arrow in Fig. 11. The stopping member 29 allows the closing member 6 of the packing to pass and then abuts against the front edge of said closing member 6, so that on grasping the gripping member 8 of the packing and drawing it out of the exposing chamber in the direction opposite to that indicated by the arrow in Fig. 11 the said closing member 6 is removed from the packing. The springy hook 31 of the changing box enters the hole 27 of the uppermost layer carrier, so that same is retained. When the packing is drawn out so far that the end of the layer carrier becomes free, the spring 82 contacts with the lower side of hook 31 and secures the layer carrier on said hook. On further drawing out the packing, the layer carrier is drawn out more and more from the packing room, till it finds an opportunity to pass the end of the top plate of the collecting chamber 12 and to repose on the bottom of said collecting chamber. The falling down of the end of the layer carrier on the bottom of the collecting chamber is secured by spring 33, which just in that moment assumes the position shown in dotted lines in Fig. 11, when the packing is drawn out so far that the layer carrier is freed. The drawing out of the pack ing is limited by the entrance of hook 3 1 into the opening 35 in the bottom plate of the packing. During the drawing out of the packing the light-tight interposition sheet 2 which is below the exposed layer carrier secures the layer carriers which are still contained in the packing against entrance of light. On pushing back the packing into the exposing box, the exposed layer carrier enters the collecting chamber 12. When the packing reaches the end of its returning movement, spring 32 is pressed downward, so that the layer carrier'is freed by hook 31 and falls down on the bottom of the collecting chamber also with that'end, which is provided with opening 27. In order to efiiect the exposure of the next layer carrier, the light-tight sheet 2 covering same is drawn out and the operations above mentioned are repeated. When all layer carriers are exposed, the door 28 of the exposing box is opened and the packing receptacle removed from the exposing chamber through door 28. The closing member 6 then remains in closing position, so that entrance of light into the packing room is prevented.

The provision of gripping openings or projections in the layer carriers allows a modification of the packing in such a manner that the light-tight interposition sheets of the layer carriers need not to be provided wit-h gripping ends extending out of the packing. The light-tight interposition sheets may be connected in this instance to the layer carriers, as illustrated in Fig. 12 of the drawing, however in such a manner that the gripping openings only penetrate the layer carriers themselves, but not the light-tight interposition sheets. In this instance it is however necessary to use a modified form of a changing box.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is:

1. A. packing for light sensitive layer carriers comprising a casing provided with a slit, a pile of loose layer carriers in said cas ing, loose substantially straight light-proof interposition sheets between the layer carriers extending through said slit which is situated in said casing directly opposite one side of said layer carriers, said interposition sheets being free from attachment with said layer carriers as and for the purposes set forth.

2. A packing for light-sensitive layer carriers comprising a two-chambered casing, one of said chambers being provided with a pile of loose light-sensitive layer carriers and substantially straight loose light-proof sheets interposed between same, said chamber being provided with a slit directly opposite one side of said pile through which the light-proof interposition sheets extend, said interposition sheets being free from attachment with said layer carriers as and for the purposes set forth.

3. A packing for loose light-sensitive layer carriers comprising a casing provided at one end with a slit directly opposite one side of said layer carriers and at the opposite end with a removable closing member, a pile of light-sensitive layer carriers within said casing and substantially straight loose lightproof sheets interposed between same, the light-proof interposition sheets extending directly in a straight line outside said casing through said slit, said interposition sheets being free from attachment with said layer carriers as and for the purposes set forth.
